Wintery conditions have forced MLS to postpone the second leg of the semifinal matchup.

HARRISON, N.J. -- Fans of New York and D.C. will have wait one more day to determine who will move on to the next round of the Major League Soccer playoffs.

A nor'easter that is affecting the New York/New Jersey area has rendered the field at Red Bull Arena unplayable due to a mass accumulation of snow. The pitch at the $200 million stadium isn't heated like many of its European counterparts and there was a legitimate concern that players could suffer an injury. The game will now be played at 7:30 p.m. ET on Thursday.

"Obviously it was a difficult set of circumstances," MLS Executive Vice President Nelson Rodriguez. "From the time we got to the arena a lot of factors were considered in originally making the decision to attempt to play on Wednesday. Looking at the forecast over time at no point was it clear that there would be so much snow and have it come so quickly. When we decided to make the effort to play we felt we owed it to everybody to see that effort through. In the end we did not feel we could get the field in to safe or playable enough condition and therefore that caused the postponement."

Wednesday's postponement marks the second time in this postseason that the Red Bulls have had to reschedule a match due to weather conditions. New York was scheduled to play the opening leg of its match against D.C. on Nov. 3 but had to swap legs due to the damage done by Hurricane Sandy.

Rescheduling the match could have massive implications for the current MLS playoff scheduling. The Eastern Conference semifinals were set for this Saturday but that could change because the two teams wouldn't have the equal amount of rest.
